Can the Frog Apocalypse be Stopped by a New “Vaccine” ? | Deep Look

In California’s Sierra Nevada mountains,
yellow-legged frogs survive at some of the highest elevations of any amphibians in North
America. As with all frogs, their skin is essential. On a hot day, they drink water through it. And they absorb the sodium and potassium their
hearts need to work. When they’re at the bottom of a lake — which
is where they spend the winter — they breathe through their skin. And those black dots ooze mucus that protects the skin from infection. But it doesn’t always work. In the late 1970s, a fungus started getting
into the frogs through their skin, moving through the water, or passed on by other frogs. Those tiny transparent beads you see moving under the microscope are spores of chytrid fungus. The spores burrow down into the frog’s skin. The skin gets irritated. Then it sloughs off. It can no longer absorb sodium and potassium. Eventually the frog dies. Chytrid fungus has been like the “black
death” for amphibians. It has decimated some 200 species around the
world. In the Sierra, chytrid fungus swept across
the mountains and in three decades killed almost every single yellow-legged frog. So scientists did an experiment to see if
they could save the species. They grew some frogs from eggs. Then they infected them with chytrid fungus. This was risky. But they hoped to give the frogs something
like a vaccine. The original experiment took place at the
University of California, Santa Barbara. Now it’s being replicated at the San Francisco
Zoo. The frogs got sick. Their skin came off. But then researchers treated the frogs with
a liquid antifungal that stopped the chytrid before it could kill the frogs. When the frogs were nice and healthy again,
researchers re-infected them with chytrid fungus. To their surprise, the Santa Barbara scientists
found that all the frogs they had immunized survived. Every one of them. Now the San Francisco Zoo has immunized 124
mountain yellow-legged frogs. And they’re returning them to their mountain lakes. [WOMAN: “There you go!”] The idea is that next time chytrid fungus ravages the lakes, as it inevitably will, these frogs
will have immunity. Some will survive. They’ll get a chance to reproduce, and maybe,
slowly, a more robust population of frogs will once again thrive here in the alpine
lakes of the sierras. Oh good, you’re still here. If science stories like this one are what

  1. what about the extinction of the fungus?

  2. Never thought I would feel so bad about frogs.

  3. I for one accept our new frog overlords

  4. Give him sum soüp

  5. Frogs
    ? Katelyn in Ky in Florida in in ky

  6. Hurray lil 🐸 froggys

  7. We learned this in our class!

  8. that doesn't even make sense , even if these frogs survive , what about the next gen , that vaccine is not gonna get inherited .

  9. If I receive vaccination for a disease, that doesn't mean it protects my offspring. Why would frogs be any different? Please explain that thinking.

  10. 0:04 frogs can be great ASMR crunching sounds

  11. 3:54 that’s so cute! Insects and my predators in harmony

  12. Honestly… I Almost Cried At The End😂😂😂I Love Animals What Else Can I Do???👌😂👌

  13. Why do our wire companies half to make our lag so bad

  14. Pray for the frogs that died from the fungus

  15. It's not slime it's mucus

  16. Glad these frogs now have a fighting chance!

  17. This is not vaccine this is variolation

  18. Such a horrible experiment. Let the nature do its work for the love of god.


  20. Frogs are so cute yet so disturbing too. I love amphibians, but I’m also glad that all of the bigger ones went extinct millions of years ago. They would have been dangerous to us when they were much larger in the past.

  21. i like chytrid fungus spores because i hate frogs

  22. I hate the scientist why did they save the frogs

  23. Dat Boi can survive anything

  24. wait a minute… Adapted immunity does NOT transfer to germ cells, so their offsprings will NOT have the same immunity. right?

  25. But… like, how long is a frogs life span? Do they pass down the immunity from the vaccination process somehow? I don't see how this solves anything long term unless they do.

  26. Oh no! Poor Froggy's! Pretty soon due to pollutants in the water and air amphibians may become extinct, that's what I heard from some other video on frogs and other amphibians, which sucks, cause I love amphibians. 💜🐸🖤

  27. Man those scienecetist are so smart for doing that for the frogs! I hope everything goes good for their experiment. 👍

  28. #deeplook #deeplook #deeplook

  29. Don't stop nature while it's destroying itself, you might regret it.

  30. nice job, scientists : )

  31. Be careful before you invent anti-vaxx frogs

  32. Mission passed
    Respect +++

  33. Anti Vaxxers have left the chat

  34. So the next generation frog will be immunized too ?

  35. how do you know we watch stuffs like this while eating

    my family offended me watching bacteria, cockroach , fly, etc. they thought disgusting while eating….

  36. Always get your kids vaccinated or their skin will fall off

  37. Janthinobacterium lividum

  38. At least Kermit isn't Anti-vaxx!

  39. Poor frogs! They're my favorite!

  40. I don't get why some humans scared to frogs they are cute

  41. Those fungus are benefits to the water ecosystem.. although it needs a dead frog body to spread and drift from the lake to the river, it has strophe that can filter water.. last food chain for the fungus, is spare by Root of three in every october-december before winter.
    Becareful of what science afflication

  42. Even nature needs vaccines..

  43. This channel needs more views!!! It is a very good documentary.

  44. On the other way around, that tiny little Chytrid fungus certainly have their rights.

  45. How does the immunity get passed onto offspring? Seems unlikely.

  46. The problem with this is that chytrid is in the environment.. So you can immunize frogs but if the environment gets re infected then the new generation will suffer again.

    I think of this as a short term solution that should definitely be taken advantage of but we mustn't give up ons searching for a more long term solution.

    I know of some salamanders who's naturally immune to the fungus. Maybe we can look at those individuals..

    Idk this is such a sad situation..

  47. Yay froggy woggys!

  48. Hope those heart eyed frogs get killed too. Basterds

  49. Anti-vax mom has left the chat

  50. video reminds me of my dog puppo biting a poisonous frog
    just happened two days ago (i think)
    please pray that my dog puppo and my other dog blitz doesn't die they're too young to die!! D:
    (we only got blitz a month or two ago and we got puppo 2 years ago)

  51. Just what we need, autistic frogs

  52. Nobody:

    Anti-Vaxxers: I sTiLl Don'T tRuSt vACcines

  53. O boy.. can you imagine anti vaxx frogs

  54. that frog at the start sounds like he's chewing crackers

  55. I wonder if their offspring will inherit their immunity like humans inherit some immunities of their parents.

  56. And this is why we need vaccines, Karen

  57. The frogs looks so cute :3

  58. Am i the only one who is scared of frogs?

  59. Im so sorry for the frog"s loss

  60. The frog at the end had a little friendo lol

  61. How would this help in the long run? It's not a genetic change

  62. Save the frogs!!!!

  63. then here comes the anti vax frogs

  64. The dislike are from anti vaxxer

  65. Everyone gangsta until there is anti-vax frogs

  66. OK antivaxxers, EXPLAIN THIS, what comes next autistic frogs?

  67. Amazing frog, they can save our in future

  68. at least we are lucky phrog Did not get infected

  69. These frogs seem to complain much less than us humans about vaccines!


  71. I when the fungus strikes back again, scientist be like: bruhh am I a joke to u

  72. If I see and antivaxxer here I will

  73. Frogs have declined from the 70s onward. My kids have never had the pleasure of going to their local pond scooping up a few tadpoles raising them into frogs and then releasing them back into the pond from which they came. We have poluted their environment.

  74. Who think deep look should have 10 million subscribers?
    Ok it's only me…..😑😑😑

  75. 3

  76. Frogs are so adorable

  77. didnt know frogs as leg fungus

  78. I bet some frogs will become anti-vaxx as their kids had autism.

  79. Duh..vaccination only works on an individual……and is not genetically passed on …..

  80. anti vax kids have left the chat*

  81. I’m just glad for once humans didn’t cause the endangerment

  82. Thats nature for you. Let the frogs die out and the stronger ones survive, its how evolution works. Im all for saving animals we almost kill, but we should let nature do its thing

  83. Then the fungus will extinct. You never think of that, do you? Do you?

  84. Anti vaxxers: im going to stop you right there

  85. This was really cool, I hope these frogs are very successful!

  86. Lol…. vaccination for frogs??? Welp. Bye bye frogs . These sort of things never work. Theres something else at play very likely caused by man lol…. the less man does… the better for these critters lol

  87. 0:33 😓😝😲😨 im shocked

  88. Always Vaccinated your frogs

  89. Even frogs take vaccines

  90. Deep look:they will survive and reproduce!. 100 years later RIP FROG SOME EATEN BY SNAKE SOME WAS INFECTED!

  91. They kill a frog for this video by demonstrating how the skin scrapes off??😖😢
